MECHANISNI FOR OPERATING PUMPS.

SPECIFICATION forming part of Letters Patent N o. 468,821, dated February 16, 1892..

Application filed March 12, 1891. Serial No. 384,835- (No model.)

To @ZZ whom it may concern.'

Be it known that we, OHARNICK lV. MC- MULLIN and WILLIAM C. DE GRAEEENEIED, residing at Jasper, Hamilton county, Florida,

have invented certain new and useful Improvements in Mechanism for Operating Pumps, of which the following is a full and complete speciicatiomreference being had to the accompanying drawings, forming part ro thereof, in which- Figure l is a sectional elevation of the apparatus in position for use. Fig. 2 is a plan View of the pump-operating mechanism apart from the pump. Fig. 3 is a transverse section I5 taken on line 3 3, Fig. 2. Fig. et is a vertical longitudinal section on line et 4, Fig. l.

The object of the invention is to provide a mechanism actuated by the passage of atrain of cars and in turn operating a pump which 2o will deliver as much or a greater quantity of water to a water-tank alongside the track as may have been delivered by the said tank into the tank of the locomotivel Theinvention consists in the several coni- 2 5 binations of parts hereinafter described and claimed.

A is a railroad-track, and o, a a a the ends of the rails between which the pum p-operating mechanism is placed.

3o B represents the frame mounted in an eX- cavation between the rail ends and consisting in longitudinal beams O C O C', transverse end beams o o c c', and central transverse beams c2 o2.

3 5 D are four bars or rail-sections, the inner ends of each pair of which are pivoted together and the outer ends of which are pivoted to the rail ends a, so that the said bars form continuations of the rails.

E is a cross-head mounted in the frame B directly under the pivotal points CZ of the bars or rail-sections D. Four plate-springs F press this cross-head up, so that the inner adjacent ends of the bars or rail-sections D will be normally elevated. The ends of the cross-head E are notched or mortised, as at e, to receive the upper beams O O and limit the vertical movement of the cross-head,V and the inner faces of the said upper beams are notched, as 5o at c3, to prevent any undue lateral movement of the ends of the cross-head. The ends of the cross-head will rest on the upper-beams C C when the bars or rail-sections are depressed to a horizontal position.

Between the two central cross-beams c2 c2, 55 below and in vertical alignment with the crosshead E, is pivoted the vertically-rocking lever G, the inner short arm of which is pivot- .ally connected by means of straps g g with the center of the cross-head, so that as the 6o pivoted rail-sections or bars are depressed by the train or elevated by the springs the said lever will be correspondingly operated. The outer end of the lever G is pivotally connected with a centrally-pivoted lever H, mounted over the well or other body of water. 'llo the ends 0f this lever Il the upper ends of the plunger-rods l are pivoted, one rod being extended upward to form the connection between the levers G H, as shown. These rods 7o I connect at their lower ends with any suitable form of pump J, discharging into the water-tank K, located alongside of the track in the usual manner. The rail-sections or bars D are each about three feet long, so that the rear truck of one car will clear them before the front truck of the next car runs thereon.

' The parts will be so proportioned that a movement of two inches at the inner ends of bars D will give-a two-foot stroke or Inore in the 8o pump, the two cylinders of which throw forty gallons each at a stroke, or, say, one hundred and sixty gallons for each car passing over the bars D. The form of springs may of course be changed, if desired, for suitablyarranged `spiral springs.

Having thus described our invention, what we claim as new, and desire to ysecure by Letters Patent, is l. The combination, with the frameand the 9o rail-sections D D, overlapping at their inner ends, of the vertically-reciprocating crosshead E, having bearings on its upper edge, to which the said overlapping ends are pivoted, and having notches or recesses in its ends to receive parallel, bars of said frame and limit the upward and downward movement of the cross-head, springs mount-ed on the frame and holding the cross-head normally raised, the pump-operating lever pivoted near its inner Ioo end beneath the cross-head, and a link g, oonnecting its inner end with the cross-head, substantially as set forth.

2. The combination, with the frame, the rail-sections D D, and the vertically-reciprocating cross-head E, mounted on the frame and to the upper side of which Jheinnerends of the rail-sections are pivoted, of the lever G, pvoted near its inner end beneath the cross-head and pivotally connected at its nner end with the Center thereof, a rocking 1ever H, carrying a pump-rod at each end and pivotally connected with the outer end of 1e- Ver G, and the springs mounted on the frame and raising the cross-head after each de- I5 pression,whereby the Weight of the train Will operate one pump-rod and the springs the other one, substantially as set forth.
